In a study published inScience(February 13, 1998) researchers have found
evidence in the ~6000-year-old coral from the Great Barrier Reef, Australia that the
tropical ocean surface was 1 degree C warmer about 5350 years ago. This work suggests that
earth may be in a long-term natural cooling trend. According to Dr. Michael Gagan, the
lead researcher, "The beginning of this interglacial period was warmer than now.
There’s been a long-term cooling trend." He also says that the natural cooling
effect may be too weak to offset human-induced global warming (The Canberra Times,
February 14, 1998).

Al
Gore's Book Has Very Strange Graph

Page 96 of "Earth in the Balance" contains a graph displaying 1
degree Celsius temperature change over 100 years, but the scale of the graph is designed
to make the change appear to be huge!

If most of the warming of the 20th century occurred before the
smokestacks of widespread industrialization appeared, how is it that the computer modelers
of climate continue to claim that the same industrialization produced the observed
warming?

When the Vikings were sailing in Arctic waters and farming in Greenland
in soil that is now permanently frozen, the question is "what caused that
warming"? It certainly wasn't manmade global warming.

Polar
Ice Caps Melting

The arctic "ice-cap" is an ocean which is frozen over and which
is surrounded by the land masses of the North American and Eurasian continents. The
northpolar ice-cap is sea ice which is floating on the ocean.

What would be the implications of that melting be then for the sea level?
Exactly none. This is simply because, as the floating ice melts, it only takes back the
sea water volume it displaced when it was floating on the water as ice.

You will notice that even though you had a substantial amount of ice in
your highball glass, the water level after the ice has melted remains the same.

The situation would be somewhat different, however, in the Southern
Hemisphere, because there the ice cap sits on a continent which is surrounded by the
oceans.

Let us assume the wintertime greenhouse warming over an area of Arctic
and Antarctic ice is 20F. During the winter, the actual temperature over most iced-up
areas is substantially below 0F. In other words, even if the temperature rose by as much
as 20F, we would still be very much below the melting point of 32F.

If the Antarctic ice shield itself melted completely, which could
only happen under much higher temperatures than from a CO2 doubling, and which would take
thousands of years because of the slowness of the response of that large an ice mass to
changed conditions, sea levels would rise by 150', a figure sometimes seen in the media.
